DUGALI) SCOTT, OF MANCHESTER, ENGLAND, ASSIGNOR TO JONES BROTHERS dz 00., OF SAME PLACE.

WOVEN DUSTER OR POLISHING-CLOTH.

SPECIFICATION forming part of Letters Patent No. 525,669, dated September 4, 1894. Application filed April 14, 1892. Serial No- 429,2l.'7. (Specimens) M Patentedin Eng December 8, 1891, No. 21 399.

To all whom it may concern.-

Be it known that I, DUGALD SCOTT, a subject of the Queen of Great Britain and Ireland, residing at Manchester, county of Laucaster, England, have invented an Improved Woven Duster or Polishing-Cloth, (for which I have obtained Letters Patent of Great Britain, No. 21,399, dated December 8, 1891,) of which the following is a specification.

The object of this invention is to produce a cheap and eflicient substitute for chamois leather intended to be used for polishing cloths, clusters, towels, or other purposes to which the same may be applicable.

Hitherto such substitutes for chamois leather and especially silver-polishing cloths have been made by weaving in the ordinary way and filling it with apolishing material, but such cloths become useless for the purpose stated as soon as the filling is exhausted or the cloth washed. According to my invention however, I dispense with all finishing, filling or dyeing and I produce a cloth which is more suitable for the purposes stated (polishing, dusting, &c.) than any of the substitutes now in use and which for my purposes is even superior to chamois leather itself.

In carrying my invention into practice I manufacture in an ordinary loom a cotton weft pile fabric which is made as what is known as a fast pile fabric so that the pile will stand washing and rough usage and so that no loose ends of pile or nap can come out in use. I then cut, crop, and brush the pile thereof and I thoroughly wash or scour the fabric to remove all stifiening matter, grease, or other impurities therefrom. I then take this unbleached fabric and I so singe the pile thereof that the fabric acquires a soft brown color most suitable in appearance for polishing cloths and dusting thereby imitating the buif color of chamois leather with out any dyeing of the yarn or woven fabric. This singeing process may precede the washing and securing if preferred. Aborder may be printed or woven round each cloth or duster or same may be otherwise ornamented as desired.

The longitudinal parts of the borders may be left uncut when cutting the pile on the central portion without any special weaving, or may be woven specially as a closely woven cloth so that such edges can be left unhemmed and will not fray out, and the transverse parts (to form the transverse bogder or edges) may be so woven that the weft cannot be cut during the cutting of the pile on the centers of the cloths; this can be easily accomplished by any expert weaver. The width or depth of these bordersii. e., from the pile surface to the edge of the cloth) may be varied according to the purpose for which the article is required. The fabric prepared as above described is then cut up along these prepared borders so as to become suitable for dusters or polishing cloths or other desired purposes, and are now ready for sale and use. In some cases I propose to weave a cloth for this purpose with the pile on both sides.

This fabric is very soft and pliable and the ends of the pile face are very open forming a brush-like surface most suitable for polishing purposes, and the processes of bleaching, dyeing, or finishing thereof are not necessary so that their cost is obviated.

'This material is not liable to become hard, greasy, or slimy, like wash-leather and can be readily cleansed by washing with hot water and soap; whereas wash-leather is most difficult to cleanse when it has once become greasy.

I am aware that a British patent toPaterson elf 001., No. 623 of 1862, shows an ordinary method of weaving a continuous weft 'pile fabric cloth of cotton or other fiber, and then finishing the same bya process of cleaning and milling; and I do not claim this. But my invention is restricted to a specific article which is woven as such, and is then subjected to a singeing operation to produce an efifect resembling chamois leather.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

As a new article of manufacture, a polishing cloth or duster, having the central portion thereof formed with an un-bleached cot- In testimony whereof I have signed my ton weft cut pile surface, and having an unname to this specification in the presence of icut surrounding edge integral therewith, two subscribing witnesses.

woven as a plain cloth fabric, the cut pile of DUGALD SCOTT. 5 such cloth being singed to a soft brown color, Witnesses:
